FLEXITANK ACCESSORIES – PE Liner
Using Extra PE/PP Liner with Flexibags: Enhanced Protection for Bulk Liquid Transport
Adding an extra Polyethylene (PE) or Polypropylene (PP) liner alongside a flexibag during bulk liquid transportation offers an additional layer of protection and functionality. This practice is especially useful in scenarios where environmental factors, container conditions, or specific cargo requirements demand heightened safety and cleanliness standards.

Key Features of PE/PP Liners
1. Material Composition:
* PE Liners: Made from high-density polyethylene (HDPE) or low-density polyethylene (LDPE), offering excellent flexibility and moisture resistance.
* PP Liners: Woven polypropylene fabric, known for its high tensile strength and durability.
2. Customizable Fit:
* Tailored to match the dimensions of standard 20-foot or 40-foot shipping containers.
* Designed to enclose the flexibag securely for maximum protection.
3. Lightweight Design:
* Easy to handle and install without adding significant weight to the shipment.
4. Multi-Purpose Functionality:
* Provides a barrier against contaminants, abrasions, and temperature fluctuations.

Applications of Extra PE/PP Liners with Flexibags
Extra liners are beneficial in several industries and use cases:
1. Food and Beverage:
* Transporting edible oils, syrups, wine, and fruit concentrates where cleanliness and hygiene are critical.
2. Chemical Industry:
* Handling non-hazardous chemicals like glycerin, latex, and detergents that require leak-proof and contaminant-free environments.
3. Pharmaceuticals:
* Ensuring product integrity for medical-grade liquids during transport.
4. Agriculture:
* Transporting molasses, liquid fertilizers, and other agricultural products susceptible to environmental factors.

Benefits of Using Extra PE/PP Liners
1. Enhanced Protection:
* Acts as a secondary barrier, safeguarding the flexibag from sharp edges, container walls, or external contaminants.
2. Improved Hygiene:
* Maintains a clean environment inside the container, crucial for food-grade or pharmaceutical-grade cargo.
3. Leak and Contamination Prevention:
* Reduces the risk of leakage or spillage reaching the container walls, ensuring safer handling and transport.
4. Extended Flexibag Lifespan:
* Reduces wear and tear on the flexibag, enhancing its durability and usability.
5. Temperature Buffering:
* Offers limited insulation against minor temperature fluctuations, aiding in product preservation.
6. Cost Efficiency:
* Protects against potential cargo loss or damage, reducing the need for expensive replacements or cleaning processes.
7. Ease of Installation:
* Quick and straightforward to deploy, with minimal labor and equipment requirements.

Installation Process
1. Container Preparation:
* Inspect and clean the shipping container to ensure it is free of sharp edges, debris, or contaminants.
2. Liner Installation:
* Spread the PE/PP liner across the container walls and floor, securing it tightly.
3. Flexibag Placement:
* Install the flexibag over the liner, ensuring alignment with filling and discharge ports.
4. Final Adjustments:
* Smooth out any folds or wrinkles in the liner and flexibag to avoid uneven pressure distribution.

Limitations
1. Added Costs:
* Using an extra liner increases initial expenses, though it provides long-term savings by reducing damage risks.
2. Volume Reduction:
* The liner may slightly reduce the effective capacity of the container.
3. Limited Temperature Control:
* While providing minor insulation, PE/PP liners are not substitutes for temperature-controlled systems.

Conclusion
Incorporating an extra PE or PP liner alongside a flexibag is a practical and efficient way to enhance the safety, hygiene, and durability of bulk liquid transport. This additional layer of protection ensures that sensitive products remain intact and uncontaminated throughout their journey. As industries continue to prioritize safety and sustainability, using extra liners with flexibags is becoming a standard practice for ensuring cargo integrity and operational efficiency.
